Abstract

PROBLEM TO BE SOLVED: To surely seal papers, and make a sealing sheet repeatedly usable by a method wherein on one surface of a transparent or semi-transparent resin sheet material having flexibility, wherein a folding line is formed along the central line, an adherent layer is formed by applying an adhesive into a stripe- form, and a release film which can be peeled is affixed on the adherent layer. SOLUTION: This sealing sheet 1 for paper is constituted of a resin sheet material 2 which is formed to be transparent or semi-transparent of a resin material having flexibility, and a release film which is affixed on an adherent layer 3 which is formed on the sheet material 2. For the sheet material 2, a folding line 5 in order to fold the sheet material 2 in two with the adherent layer 3 side into a valley-form, is provided, and rounded parts 6 are formed. The adherent part 3 is formed by applying an adhesive into a large number of lines in parallel. By this method, anybody can seal papers at any place at a low cost, and the sealing sheet can be repeatedly used.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet for sheet sealing suitable for sealing sheets.

[0002]

2. Description of the Related Art Conventionally, as a means for sealing a paper piece (paper) such as a business card, the paper is wrapped in a bag-like or sheet-like resin film, and the free edge portion of the resin film is thermally welded. Methods are known.

[0003]

However, the above-mentioned means requires a device for heat welding, so that the cost is high and the place where the sealing operation can be performed is limited. Also,
If air pockets are formed between the paper and the resin film during thermal welding, it is difficult to remove them after welding.
Further, the resin film is used only once and cannot be used repeatedly.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sheet sealing sheet which can be used to securely seal a sheet anywhere and can be used repeatedly.

[0005]

In order to achieve the above object,
The sheet for sheet sealing according to the present invention is obtained by applying an adhesive to one surface of a transparent or translucent flexible resin sheet material having a folding line formed along a center line, in the form of a plurality of parallel stripes. The adhesive layer is formed and a peelable release film is adhered on the adhesive layer.

It is preferable that the adhesive layer has releasability from paper.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 and 2, the sheet for sheet sealing (1) according to the present invention is made of a resin sheet material (2) formed of a transparent or translucent resin material having flexibility such as polyester. ), An adhesive layer (3) formed on the entire surface of one of the front and back surfaces of the sheet material (2), and an adhesive layer (3) for protecting the adhesive layer (3) until use. And a release film (4) made of polyethylene or the like adhered thereon.

The sheet material (2) has a rectangular shape, and a folding line (5) for folding the sheet material into two with the adhesive layer (3) side as a valley is provided at the center. 4 of the resin sheet (2)
An arcuate round part (6) is formed at the corner,
As shown in an enlarged manner in FIG. 3, when the round portion (6) is folded in two at the bending line (5) and the round portions (6 a) and (6 b) are overlapped with each other, the round portion (6 a) )
One radius of curvature is slightly larger than the other radius of curvature so that (6b) draws a different contour.

The pressure-sensitive adhesive layer (3) is formed by applying the pressure-sensitive adhesive (3a) in a multi-parallel streak shape. FIG.
For example, the adhesive (3a) is continuous so as to cover the entire surface of the sheet material (2), and the adhesive (3a)
(3a1) are formed to project in the form of a plurality of parallel stripes. The space between the swells (3a1) is a flow path (3b) that allows air to flow. The adhesive (3
As a), one having a property of being peelable from the paper (7) to be hermetically sealed and of maintaining the adhesiveness after peeling is used.

The sealing sheet (1) having the above structure is used as follows. First, the release film (4) is peeled off to expose the adhesive layer (3), and in this state, as shown in FIG. 1, two sheet pieces (2
a) A paper sheet (7) is placed on one sheet piece (2a) of (2b). Next, the sheet material (2) is folded at the folding line (5) to be folded in two, and the sheet pieces (2a) (2b)
Adhere each other. Thereby, as shown in FIGS. 4 and 5, a sealed body (9) in which the paper piece (7) is sealed can be obtained. When pressure is applied to the adhered sheet pieces (2a) and (2b), the adhesive layer (3) is crushed and the air flow path (3b) is filled with the adhesive (3a). It is possible to increase the degree of adhesion to the sheet or paper piece (7) of the other party.

In the sealed body (9), since the paper piece (7) is adhered to the sheet pieces (2a) and (2b), the positional deviation of the sealed paper piece (7) can be surely prevented. . Further, as described above, since the adhesive (3a) is applied in a streak shape, even when air (bubbles) remains between the sheet pieces when the sheet pieces (2a) and (2b) are overlapped with each other. This can be pushed out through the flow path (3b) of the adhesive layer (3). Therefore, the degree of adhesion between the sheet pieces (2a) and (2b) can be increased to obtain a reliable sealing effect. FIG. 1 illustrates a case where the application direction (stripe direction) of the adhesive (3a) is parallel to the bending line. However, the same effect can be obtained even when the adhesive (3a) is applied in a direction perpendicular to this direction. FIG.
As shown in (2), if a notch (slit: 10) is formed in a part of the bending line (5), the air escapes from the notch (10), so that the air can be pushed out more easily. The bending of the sheet pieces (2a) and (2b) can be further facilitated.

[0013] Further, a round portion (6a) overlapping after sealing.
(6b) Since the curvatures of the two pieces are changed, even when the sheet pieces (2a) and (2b) are peeled off at the time of re-use, the radius of one sheet piece is easily caught by a finger,
It can be easily peeled off.

In the present invention, the pressure-sensitive adhesive (3a) is applied in a streak shape. However, it is also possible to apply this in a dotted shape.
However, in this case, it is difficult to push out the air,
Further, it is not preferable because there is a problem that characters and the like described on the paper piece (7) are difficult to see.

[0015]

According to the sheet sealing sheet of the present invention, a transparent or translucent flexible resin sheet material having a bent line formed along the center line is coated with an adhesive on one surface of a plurality of parallel strips. Since the adhesive layer formed by applying the adhesive layer is formed and a peelable release film is adhered on the adhesive layer, it can be carried, and a welding device or the like as in a conventional product can be used. Since it is not required, anyone can seal the paper at low cost anywhere.

If the adhesive layer is provided with a releasability for paper, it can be used repeatedly.
